Abstract

The purpose of this invention is to reduce an artifact on an image that is caused by a gradient magnetic field error, in a non-orthogonal sampling method. For the purpose, when data used for an image reconstruction is obtained, data for correcting an error caused by a gradient magnetic field is obtained and the data used for the image reconstruction is corrected using the obtained correction data. In order to obtain the data for correcting the error, a block having a plurality of parallel echo signals is measured.
